fjmzgezeF-HA in lll . by salidcam. body, i ai s the lever may also he soinade that only one end ol the pirn is wound to ,torni a cone whilst the other is straight.

The present. pirn Winder is oi a compact design and yet permits to wind pirns or' a great length.

Obviously cylindrical pirns may be wound as Weill as conical pirns in the described inanner, i. e. having one or tivo conical ends.

This is accomplished as follows:

As shown, it is supposed that the pirn tube -`all is conical, thus determining the hasic lorin (conical.) of the pirn. Thetubc del and the pirn S as it is Wound thereon is pressed by the pivoted springurgcd stirrup 38 against the cylindrical friction roll i3. This stirrup 38 is pivoted at 39 and also on spin die Ail, forming two rectangular axes.

As shown, thelever 8 is vibrated on its pivot l with decreasing amplitude and thc pirn Will have bothends conical.

By placing pivot 6 inthe hole 3, Fig.'2,`of the link lever 8 the pivot point is shifted closer to the caniSO, so that lever 8 will cause the formation of a pirn having its butt end or larger end of a shorter taper than the smaller front end. i

Then the lever S does not swing beyond a perpendicular from the thread `guide rod l passing through the pivot point 4, the nirn is then tapered only at one end, namely the smaller end; non itl?, instead of using a conical cop tube Llei, a cylindrical tube is used mounted in the stirrup 3S, the pirn is `given cylindrical torni, and may be inade tapered on both ends, in the position of the parts shown in Figs. l and lt the pivotl' is shifted, as heiore descrihech lo il, then this cylindrical pirn will have a greater taper at one end than at the other, nhilc if the lever n he given a lnovement so that the part carrying roller l) Awill lie vibrated only in one direction trom its initial or starting position, the cylindrical piru will he tapered only at one end, the left hand end Fig. l. i `l claim: i

l. A pirn Winder for producing pirns having at least one conical end, comprising in `combination a traversing thread guide, a link lever turnable about a stationary pivot and operatively connectedto said thread guide, a cai-n body, a, slide ada-plted to be reciprocated ifdngi pieceA to. which a,

resale? reciprocating motion is imparted hy said slide, said sliding piece being directly coupled with said link lever and said slide, und nicansl adapted to :1utoznalically displace said .slidingl piece 'relatively lo said link lever l'or gradually reducing' the stroke nl" the thread guide.

A pirn ninder 'lor producing pirns having at least one conical end, comprising in combination, a traversing thread guide, a slotted lever turnable about a stationary pivot and operatively connected to said thread guide, a cani body, a slide provided with a slot and adapted to be reciprocatcd by said cani body, a sliding piece, alpin on said sliding piece coope 1ating with said slotted lever and the slot in said slide, whereby an oscillating motion inniarted to said slotted lever and thereby a reciprocating inotion to said thread guide, and means adapted to automatically displace said sliding piece relatively to said slotted lever for gradually reducing the stroke of the thread guide.

3. A pirn Winder lor producing pirns having at least one conical end, comprising in conibinatimi, a traversing thread guide, a slotted lever turnahle about a stationary pir* ot and operatively connected to said thread guide, a cani body, a slide provided with a |slot and adapted to be recipro 'ated by said cain body, guide means carried On parallel links, a sliding piece slidalily mounted on said guide means, a pin on said sliding piece cooperating "with said slotted lever and the slot in said slide whereby an oscillatingl inotion is imparted to said slotted lever and thereby a reciprocating motion to said thread guide, and means adaptedto automatically displace said guide means and thereby said sliding piece relatively to said slotted lever for gradually reducing the stroke of the thread guide.

et. A pirn Winder for producing pirns having at least one conical end, comprising in combination, a traversing thread guide, :i slotted lever turnahle about a stationary pivot and ope `ativcly connected to said thread guide, a cani body, a slide providfid with :1 slot and adapted to he reciprocated hy said cani body, guide 111eans carried on parallel links, a sliding piece slidably n'iouilied on said guide means, a pin on said sliding picco cooperating with said slotted lever and the slot in said slide whereby an `oscillati11g niotion is imparted to said slotted lever and thereby a reciprocating motion to said thread guide, and means adapted to automatically displace said guide means and thereby said sliding piece relatively to said slotted lever for gradually reducingr the stroke 'of the thread guide, said means including a cani face in rigid connection with,` one oi said parallellinks andan abutment member cooperatingiwithsaid cani face.

5. Afpitn widder comprising in combina- Elli relatively to said link lever for gradually re- 10 ducing the stroke of the thread guide, and

means to permit the shifting of tlie pivot point ot' said lever to change the shape of the pirn ends.

In testimony whereof, I have signed my 15 name to this specification.
